What are some ways that peers can influence your health both positively and negatively?

At school for example: you're constantly around other students eating junk food everyday which becomes the norm. However, when you bring something helathy sometimes people will pick on your lunch because they're jealous they don't have your eating habits. Or because it's not normall to see people eating healthy in the cafeteria.

the last statement is correct i.e.

when your heart is not pumping enough blood around your body because your heart is severely failing, you may need an artificial heart. an artificial heart is a mechanical device, about the size of an orange, that is connected to your heart or implanted in your chest to or replace a failing heart.
